For that game you will be looking at a minimum of $150 for a seat in the upper 200s...if you are lucky. $150 will get you a seat in the 300s and 400s, but those sections are waaaaay up there and/or behind the basket. I am always on StubHub buying my tickets for Knick games and I can tell you for that game do not expect to get in the door for anything under $150.
Advice: look for sections 221/222...226/227. Towards the ends of the court, you do not feel like you are way up atop Mt Everest, the seats face the team benches. A very good seat and the prices in those sections always seem to be about right. (Well about as right as right can be when you know you are being ripped off. 150 dollars for a Knick game is about 130 dollars too high.)
Good luck, and don't buy early. Look to StubHub a day before game -- prices will be cheaper and don't worry, seats will be available. You can do even better if you show some backbone and look to buy just an hour or two before game time. I've done that and got myself some tickets in that nice 222 section for just fifty bucks. Yes, it was a game against the lower than low 76ers, but I did get to see Bargnani fly through the air, fall flat on his face, and for all intents and purposes, end his Knicks career. That was worth $50.
